BACKGROUND
The coronavirus 2019 (COVID-19) pandemic led to frequent schedule changes, abbreviated seasons, and disrupted training at all levels of organized sports.
PURPOSE/HYPOTHESIS: The purpose of this study was to investigate the epidemiology of sports-related injuries at a single National Collegiate Athletic Association (NCAA) Division I institution during the 2020 COVID lockdown season when compared with pre-COVID seasons. It was hypothesized that there would be an increase in the overall injury rate and an increase in the number of days missed because of injury during the 2020 season when compared with the previous seasons.
STUDY DESIGN
Descriptive epidemiology study.
METHODS
The injury surveillance database at a single NCAA Division I institution was queried for injuries that resulted in time loss (missed game or practice) for a student-athlete or for injuries that persisted >3 days. Injuries were categorized by anatomic area. Days unavailable because of injury were recorded as total days that a student-athlete was listed as "out of activity." Injury incidence and days unavailable, per 1000 athlete-exposures (AEs), were calculated for 3 pre-COVID seasons (2017-2019) and the 2020 season. The authors calculated the injury rate ratio (IRR) and its associated 95% CI of the 2020 season in comparison with those for the pre-COVID seasons.
RESULTS
Compared with the pre-COVID seasons, the total injury incidence increased by 10.5% in the 2020 season (68.45 vs 75.65 injuries/1000 AEs; IRR, 1.11 [95% CI, 1.08-1.13]). Total days unavailable decreased by 20.7% in the 2020 season (1374 vs 1089 days/1000 AEs; IRR, 0.79 [95% CI, 0.77-2.26]). Compared with women's teams, men's teams had a larger increase in total injury incidence (16.4% vs 6.5%) and larger decrease in days unavailable (23.7% vs 10.75%). There were no clear trends to changes in anatomic distribution of injuries, either by sport or between the sexes.
CONCLUSION
Compared with the pre-COVID seasons, the injury incidence was higher and the number of days missed because of injury lower among collegiate student-athletes at a single NCAA Division I school in the season immediately after the COVID-19 lockdown.
背景
2019年冠状病毒病（COVID-19）大流行导致各级有组织体育赛事的赛程频繁变动、赛季缩短以及训练中断。
目的/假设：本研究的目的是调查在2020年COVID封锁赛季期间，一所美国国家大学体育协会（NCAA）一级机构与COVID之前的赛季相比，与运动相关损伤的流行病学情况。研究假设是，与前几个赛季相比，2020赛季的总体损伤率会增加，因伤缺训的天数也会增加。
研究设计
描述性流行病学研究。
方法
查询一所NCAA一级机构的损伤监测数据库，以获取导致学生运动员缺训（错过比赛或训练）或持续超过3天的损伤情况。损伤按解剖部位分类。因伤无法训练的天数记录为学生运动员被列为“停止活动”的总天数。计算了3个COVID之前赛季（2017 - 2019年）和2020赛季每1000次运动员暴露（AE）的损伤发生率和无法训练的天数。作者计算了2020赛季与COVID之前赛季相比的损伤率比值（IRR）及其相关的95%置信区间。
结果
与COVID之前的赛季相比，2020赛季的总损伤发生率增加了10.5%（68.45例/1000次AE对75.65例/1000次AE；IRR，1.11 [95%置信区间，1.08 - 1.13]）。2020赛季因伤无法训练的总天数减少了20.7%（1374天/1000次AE对1089天/1000次AE；IRR，0.79 [95%置信区间，0.77 - 2.26]）。与女子队相比，男子队的总损伤发生率增加幅度更大（16.4%对6.5%），因伤无法训练的天数减少幅度也更大（23.7%对10.75%）。无论是按运动项目还是按性别，损伤的解剖分布变化均无明显趋势。
结论
与COVID之前的赛季相比，在COVID-19封锁后的第一个赛季，一所NCAA一级学校的大学生运动员损伤发生率较高，但因伤缺训的天数较少。
